This game had its release 3 years ago. One could say that they had a time to cope with issues. Now they do nothing, simply waiting when people will give up and go to another games, therefore 'lower the congestion' and it will happen, because paying for game with I cant play is a little bit stupid.
There is no inactive kick system implemented so all people just wont log out knowing that they wouldn't be able to lo back in. It is a faulty approach, and devs doesn't communicate at all. Or making a posts like:
